Comet C/2019 H1 (NEOWISE) brightness

The observed magnitude
and coma diameter
values are derived from the Comet Observers Database
by averaging the values reported in recent observations (more recent than 4 days), when available. The Estimated Magnitude
comes from the JPL Horizons ephemerides service and might be
inaccurate given the highly dynamic and unpredictable
behvior of comets. When available, please refer to the Observed Magnitude value and consider the Estimated Magnitude as a
directional indication. We acknowledge with thanks the comet observations from the COBS Comet Observation
Database contributed by observers worldwide and used in this table to
report recent comet observations.

The following chart is the predicted light curve
(visual magnitude as a function of time) of Comet C/2019 H1 (NEOWISE),
according to the most recent ephemerides data.
Magnitude data is sampled with a 2 days interval and there might be inaccuracies
for objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepancies
between the observed and predicted brightness because of their highly dynamic behaviour.

Comet C/2019 H1 (NEOWISE) rise and set times

The rise and set times are defined as the time at which the upper limb of Comet C/2019 H1 (NEOWISE) touches the horizon,
consideting the effect of the atmospheric refraction. As the atmoshpere conditions cannot be modeled precisely the
times reported here should be considered correct with an approximation of few minutes.
